Inflammatory bowel disease (IBD) is a chronic nonspecific inflammatory gastrointestinal tract disease. Sarcopenia is one of the most easily overlooked complications of inflammatory bowel disease, which can lead to decline of therapeutic efficacy and poor prognosis of patients. Therefore, the inclusion of assessment and prevention of sarcopenia in the treatment of inflammatory bowel disease is of great importance in clinical practice. This article reviewed the presence of sarcopenia in inflammatory bowel disease.

Nonalcoholic fatty liver disease (NAFLD) is a clinical syndrome characterized by hepatic steatosis and fat deposition in hepatocytes in the absence of significant alcohol use. A growing number of studies have shown significant dysregulation of intestinal microbiota in patients with chronic liver disease and cirrhosis. Small intestinal bacterial overgrowth (SIBO) is a clinical syndrome induced by excessive bacteria in small intestine. This article reviewed the correlation between SIBO and NAFLD, as well as the effect of probiotics on treatment of NAFLD.

Objective To investigate and evaluate the changes of T lymphocytes and red cell immunity of peripheral blood in patients with primary hepatocyte carcinoma (PHCC) after radiofrequency ablation(RFA) treatment. Methods The pre- and post- RFA(3d,7d,14d) peripheral blood T lymphocyte subsets(T3,T4,T8,T4/T8) and red cell immunity (RBC C3 receptor flower and RBC-immuocomplex formation rate) were investigated in 120 patients with PHCC treated by RFA. Results On 7d, 14d after RFA, T3, T4 lymphocytes and T4/T8 were higher than those on preoperative day significantly(P

Objective To explore the pattern of functional reorganization in the cortex after corticospinal tract ( CST) injury and its relationship with the recovery of upper limb motor function. Methods Fifteen patients with complete paralysis on one side after acute cerebral infarction were studied. Within 1 week after the onset, func-tional magnetic resonance imaging ( fMRI ) and diffusion tensor tractography ( DTT) were performed in parallel with timed finger flexion and extension movements in all subjects. The number of nerve fibers in corticospinal tract ( CST) in the affected and healthy sides was measured by using Dtv.Ⅱ. R2 software. One and three months later, fMRI was performed while the affected fingers were flexed and extended passively and any cortical activation was observed. In addition, Fugl-Meyer arm motor function scores were assessed one week, one month and three months after the stroke. Results According to the reconstructed nerve fiber number in CST on the affected side, the patients were classified into three types. Type I:the number of newly-built CST nerve fibers is more than 2/3 of that on the healthy side;type II:the ratio is between 1/3 and 2/3;and type III:the ratio is less than 1/3. For typeⅠpatients, blood oxygenation level-dependent fMRI ( bold-fMRI) showed initial activation of the bilateral sensorimotor cortex ( SMC) and the sup-plementary motor area ( SMA) on the affected side. That was followed by a gradual decrease in the activity in the healthy SMC and an increase in the affected SMC at 1 and 3 months. Among the type II patients bold-fMRI indicated activation of the SMC and SMA on the affected side initially, significant activation of the bilateral SMC and SMA one month later and then stronger activation in the SMC on the healthy side and a weakening of activation in the SMC on the affected side. For typeⅢpatients, initially the SMA and the posterior parietal cortex were found to be slightly ac-tivated. One month later SM1 on the unaffected side was slightly activated, and 3 months later neither the SMC nor the SMA on either side was activated. One week after the onset, the average upper extremity FM scores of the three types of subjects were not significantly different. After one month the three groups′averages were all significantly dif-ferent from one another. But after three months the averages for types I and II were again not significantly different, but significantly better than the average of the type III patients. Conclusion Different CST injuries induce different modes of cortical reorganization. The reorganization is a dynamic process, and different activation patterns are closely correlated with clinical prognosis.

AIM: To prepare glycine liposome microparticle and observe the effect of glycine liposomes on cardiomyocyte injury induced by hypoxia/reoxygenation. METHODS: (1) Reverse-phase evaporation method was used to produce glycine liposomes, the effects of different organic solvents: aether, chloroform and two mixtures of aether/chloroform on entrapment efficiency were evaluated, transmission electron microscope was used to detect the particle diameter of glycine liposomes. (2) A cardiomyocyte injury model was established by using hypoxia/reoxygenation, the activities of lactate dehydrogenase (LDH), creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) of each group were detected. RESULTS: The entrapment efficiency of glycine liposomes prepared with the mixtures of aether/chloroform is highest compared with other organic solvents (64.8%, P

Objective To summarize our experience in the diagnosis and treatment of thyroid Hurthle cell neoplasms. Methods Clinical data of thyroid Hurthle cell neoplasm patients admitted from 1972 to 2003 were analyzed retrospectively. Results The main symptoms were thyroid solitary node or mass (37 cases) and multiple nodule (9 cases). 4 cases had cervical lymph node metastasis. With BUS、CT、ECT and FNAC,only 10 cases were diagnosed as HCNs preoperatively, 36 cases were misdiagnosed as nodular benign single or multiple node. Twenty-eight cases were diagnosed by FNAC and quick freezing pathology. Benign HCNs was treated by isolateral thyroidectomy and malignant HCNs by additional contralateral subtotal thyroidectomy. Eighteen cases were diagnosed by postoperative paraffin pathology, and retrival second operation was performed according to the benignity or malignancy of the thyroid lesion. All cases were followed-up for 2 to 10 years and doing well without recurrence. Conclusions We should realize thyroid Hurthle cell neoplasms fully, if HCNs is suspected intraoperatively, quick freezing pathology is helpful. With appropriate therapy, the prognosis is satisfactory.

Objective To summarize MRI findings of focal cortical dysplasia (FCD), analyze MRI characteristics of various pathological subtypes of focal cortical dysplasia. Methods Forty-four patients with FCD were collected. Their MRI findings were analyzed retrospectively. According to pathologic findings, these patients were divided into FCD type Ⅰ group and FCD type Ⅱ group. The following MR signs were observed in the two types of FCD: ( 1 ) Focal thickening of the cortex. ( 2 ) Blurring of the gray matter-white matter junction. ( 3 ) Tapering of white matter signal intensity alteration toward the ventricle on FLAIR and on T2WI. (4)Focal brain hypoplasia. (5)Increased signal intensity of gray matter on FLAIR. (6)Increased signal intensity of gray matter on T2 WI. ( 7 ) Increased signal intensity of subcortical white matter on FLAIR.(8) Increased signal intensity of subeortical white matter on T2WI. (9) Decreased signal intensity of subcortical white matter on T1 WI. The χ2 tests and corrected χ2 tests were used for comparison between the two groups. Results In the 44 cases, there were 30 cases with FCD type Ⅰ and 14 cases with FCD type Ⅱ. FCD was identified by MRI in 32 cases. Blurring of the gray-white matter junction is the most common sign of FCD (23 cases). There were 21 cases identified by MRI in FCD type Ⅰ group. Focal brain hypoplasia is a typical sign of FCD type Ⅰ , which was found in 11 cases in FCD type Ⅰ group but none in FCD type Ⅱ group. There was statistically significant difference between the two groups (continuity corrected χ2 =5. 0286,P =0. 0249) . In FCD type Ⅱ group, 11 cases were identified by MRI. Increased cortical thickness was found in 10 eases in FCD type Ⅱ group and 11 cases in FCD type Ⅰ group ( χ2 =4. 6234 ,P =0. 0315). Increased signal intensity of subcortical white matter on FLAIR was found in 9 cases in FCD type Ⅱ group and 7 cases in FCD type Ⅰ group (χ2 =6.9180,P =0.0085). Tapering of white matter signal intensity alteration toward the ventricle was found in 4 cases in FCD type Ⅱ group and none in FCD type Ⅰ group ( continuity corrected χ2 = 6. 2883, P = 0. 0122). The above-mentioned three MRI findings showed statistically significant difference between the two groups and were features of FCD type Ⅱ.All of the other MRI findings showed no statistically significant difference between the two groups. Conclusions Different pathological subtypes of FCD have different MRI characteristics. It is helpful to make preoperative diagnosis and planning.

Objective To investigate the pattern of the cerebral white matter lesions in patients with mild and moderate Alzheimer's disease(AD)and healthy controls using proton magnetic resonance spectroscopy(~1H-MRS)and diffusion tensor imaging(DTI).Methods Twenty AD patients and Twenty healthy controls were recrnited.All subjects underwent clinical examination,neuropsychological assessment.The quantitative analysis of N-acetylaspartate(NAA),myoinositol(mI),Chotine(Cho)and Creatine(Cr)resonance signals in region of interests(ROIs)located in the paraventricular white matter region bilaterally were measured.Ratios of NAA/Cr,mI/Cr and Cho/Cr were calculated in two groups.In addition,conventional MRI and DTI scanning were received,fractional anisotropy(FA)and mean diffusivity(MD)values of white matter in the same regions were measured respectively.Results No significant difference between two groups were observed in NAA/Cr ratio(P＞0.05).A significantly increased mI/Cr and Cho/Cr were found in AD patients than in controls(P＜0.05).FA and MD values in AD patients were 0.470±0.082 and 0.771±0.099,and in controls were 0.539±0.068 and 0.691±0.064,respectively.FA value decreased significantly in AD patients(P＜0.05),M D value increased significantly in AD patients(P＜0.05).After controlling for age-related,partial correlation analysis revealed a negtive correlation between mI/Cr and FA value in the patients with AD(P＜0.05).No correlation between mI/Cr and MD was found(P＞0.05).Conclusion The results suggest that not only the gray matter is injured,but also the white matter is abnormal in AD patients.Combining ~1H-MRS with DTI alterations could provide the valuable informations about white matter lesions in AD patients.
